NAME

xgrab - interactive front for xgrabsc, an X-Windows image grabber

SYNOPSIS

xgrab

DESCRIPTION

xgrab lets you grab arbitrary rectangular images from an X server and writes them to files or commands (such as lpr) in a variety of formats.

xgrab is a front for the xgrabsc program. Read the man page for xgrabsc for a description of the options presented by xgrab. The xgrabsc program has more options than are presented through the xgrab interface. In particular, xgrab does not allow you to grab areas of the screen by specifying numeric coordinates, or grab subareas of a window through offset coordinates.

After selecting options from the various categories presented, press the OK button to have xgrab run xgrabsc to let you grab an image from the screen. After you press OK, xgrab's window will disappear and xgrabsc will gain control until the grabbing process is finished. Afterwards, the xgrab window will reappear.

OPTIONS

Xgrab responds to the standard application options, such as -display. See the man page for X for a complete list.

You can also override the default xgrab settings in your .Xdefaults. See the examples section below for instructions.

RESOURCES

The XGrab resource file, XGrab.ad, contains a complete specification of the resources of all the widgets used in the xgrab window. Global resources, such as default font and color, are at the bottom of the file.

EXAMPLES

The To Command output option may be used to pipe xgrabsc output to programs. The most common commands are lpr for Postscript output, and xwud for X-Window Dump output. Programs that do not accept piped input should not be used in To Command.

You can also get fancy and pipe the output through more than one command, such as tee screen.dmp | xwud, to store the grabbed image and get a preview window.

Default settings for xgrab can be made in your .Xdefaults file. For the Athena toolkit version of xgrab, Toggle buttons can be set/unset through their .state attribute, and text field strings can be set through their *string attribute. For the Motif toolkit version (which has diamond-shaped buttons for radio buttons), toggle buttons can be set/unset through their .set attribute and text field strings can be set through their *value attribute.

For example, to set the default paper size for postscript output, put these lines in your .Xdefaults (and use xrdb to load them into the server!):

XGrab*.pageWidthText*string: 8.5
XGrab*.pageHeightText*string: 11.0

or

XGrab*.pageWidthText*value: 8.5
XGrab*.pageHeightText*value: 10.0

To set the default output type to XWD, put these lines in your .Xdefaults:

XGrab*.ps.state: 0
XGrab*.xwd.state: 1

LIMITATIONS
